When was the first Chinese Rocket invented?
Around 499 AD. The Chinese ignited saltpeter, sulfur and charcoal in hollow bamboo tubes to shoot projectiles - including rats. These rockets were actually called 'flaming rat rockets'.
Can space rockets be stopped once ignited?
Depends on the type of fuel being used, solid rocket fuel can not be turn off, liquid fuel can.
What is the difference between solid rockets and liquid rockets?
There are two main types of rockets: liquid-fuel and solid-fuel. Liquid-fuel rockets consist of a fuel and oxygen (or other oxidizer) in liquid state. They are combined in a combustion chamber and ignited. The fuel flow to the engine can be controlled, the amount of thrust produced can be regulated and the engine can be turned off or on as needed. Solid-fuel rockets consist of a fuel and oxidizer that are pre-mixed in a solid form. Once the solid fuel is ignited, the resulting thrust cannot be regulated or turned off. This fuel system is simpler, safer, and cheaper-but less efficient-than that of a liquid-fuel rocket.
What needs To burn fuel in rocket?
You need a fuel. You need something that will react or "burn" with it. This is called an oxidizer, even though oxygen is not always what is used. You need a means of forcing the fuel into a combustion chamber. You need a combustion chamber. And you need an exhaust bell for the spent fuel to leave! Some rockets need an igniter, something to set the fuel and oxidizer off. Other rockets use "hypergolic" fuels, which means that the fuel and oxidizer go off just by coming into contact. This is good because not having an igniter means one less thing that can go wrong. The lunar module had this kind of engine. Solid rockets have the fuel and oxidizer mixed together, just waiting to be ignited. The burning fuel hollows the rocket out, forming a sort of combustion chamber.
Do rockets need fins in space?
Yes. For aerodynamic reasons.
Do rockets need energy?
Yes, rockets need energy for launching

How are rockets useful?
Because if we didn't have rockets there would be no such thing as rockets and we need them because the word "Rockets" sounds like pockets and we like words that rhyme don't we.
What do rockets need to burn fuel?
they need water.
Why have rockets?
You need rockets so you can travel to space and visit other planets. Without rockets we would know nothing about astronomy.
What are solid rockets?
The correct term is "solid propellant rocket". These are rockets that burn fuel that is not a liquid(or they are NOT liquid fuel rockets). These rockets have a fuel that is poured into the rocket case and turns to a solid. Once ignited, there is no stopping the burn or controlling it.A simple example of this is rocket you shoot on the 4th of July. It burns black powder that has been formed into a cardboard case.Whereas, a liquid fuel rocket can be controlled by varying the amount of fuel that is injected into the rocket motor.
What types of products does Estes Rockets provide?
Estes rockets is a great company for kids! Their main product are model rockets and associated rocket engines that can be launched for fun. Their rockets used to be sold as kits but they now offer a fully assembled line. Their engines are labled with a letter, then a number, dash, and number, e.g. C6-7. The first letter is power, the number is length of burn time and the last is the delay until the parachute charge is ignited.
Need variety name for electrical tech fest?
IGMI(ignited minds)
Can rockets be launched in vacuum?
Yes. Rockets have both a fuel and an oxidizing agent, so they don't need air.
How did rocket fuel contribute to the Hindenburg disaster?
It didnt. Liquid Oxygen is what rockets use for fuel however the Hindenburg was filled with ahighly reactive gas called hydrogen which ignited shortly after the Hindenburg crashed.
